Virtual Clinical cases are effective interactive tools for assessing clinical skills, simulating various aspects of doctor patient interaction. The aims of this study were to develop and psychometrically validate a virtual tool to assess knowledge about the diagnosis and rational treatment of diabetes mellitus, based on its pathophysiology, in a computer graphical user interface, and to propose a model of support for teaching, in order to promote Telecare and Tele-education. This was a methodological development study with a quantitative approach. The virtual clinical cases were applied to a group of 14 doctors from a universe of 60 Endocrinologists (experts) and to another group of 72 third-year medical school students. The process followed the guidelines for the evaluation of psychometric properties with descriptive and inferential analyses. For reliability analysis, Cronbach's alpha was applied to expert, student and all-group questionnaires (,890: ,606: ,770). The difference in scores between experts and students was highly significant by Friedman (p > 0.01) and Wilcoxon (p > 0.001) tests. From the analysis of the scores, a manual for regulation of VCC and a graphical interface in virtual clinical case format (simulation) were created, linked to a database hosted on the Telehealth system – Goiás Federal University of Goias platform. The instrument is easy to understand and to use by subjects. When applied to students and medical professionals, the instrument also fulfills a function of process evaluation parallel to the formative process and can also be useful in continuing education in the FHS. In summary, the VCC resulted in an instrument with proven psychometric properties and features, and can therefore be considered a valid and reliable instrument to measure knowledge about the diagnosis and rational treatment of DM based on its pathophysiology. The project has pioneered, since there was not an online tool, developed and previously validated for reviewing of clinical cases. We intend to continue this project expanding its use for formative assessment and continuing education in other specialties of internal medicine.
